Voltage Drop Testing
Test the voltage drops caused by the switch, cable, solenoid or connector. Any abnormal voltage
drop generally results from an additional resistance. The resistance will restrict the currents upon
the start of the engine, leading to the reduction of the load voltage of the battery and the slow-down of
the start of the engine.
1. Cut off the ignition system so as to disable the start of the automobile.
(Cut off the main ignition coil, shunt coil, cam and starting sensor so as to cut off the ignition
system. Operate by reference to the automotive manual.)
2. Set the rotary switch to DCmV or DCV. Insert the red test lead into the A terminal and the black
